RODENTEXTERNHNATOR.

.To aJ/Z- whom, t may concern:

Be it known that I, MARION T. WHITNEY, a citizen of the United States,residing at Portland, in the county of Multnomah and Stateof Oregon,have invented certain new and useful Improvements inRodent-Exterminators g and I do declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention is an improved rodent-exterminator for exterminatin moles,gophers, and other burrowi'ng animaIs, as hereinafter described.

In the accompanying drawings, Figure 1 is an elevation of my improvedrodent-exterminator, showing the same in position for use. Fig. 2 is alongitudinal sectional View of the same. Fig'S is a transverse sectionalview of the same.

My improved rodent-exterminator is a torpedo to be exploded undergroundin the bur row of the animals for the purpose of emitting noxious gasesand of forcing such gases, together with smoke, through the variousramifications of the burrows for the purpose of destroying the animalstherein.

My improved torpedo or exterminator consists of a paper or othersuitable wrapper 1, which is rolled upon itself to form spiralconvolutio'ns which extend from end to end thereof, the spaces betweenthe convolutions being filled with an explosive powder com posed ofsulfur, charcoal, and saltpeter in such proportions as will make a densesmoke and will explode with force enough to drive the smoke and gasesthrough the various ramifications of the burrow or burrows.

Specification of Letters Patent.

Application filed September 14,1905. Serial No. 278,506.

Patented Sept. 25, 1906.

In making the torpedo or exterminator the powder is placed on thewrapper and the latter is then rolled to form the coils with the powderbetween them. In the center of the torpedo, at one end thereof, isplaced a suitable fuse b. The ends of the torpedo are closed and securedby suitable bands 3, which are here shown as made of cord.

In using the exterminating-torpedo the fuse of the same is ignited andthe torpedo is placed in the burrow, the entrance of which is thenclosed with earth, which is tamped. When the torpedo explodes, the smokeand gases are driven by the force of the explosion entirely through theburrow and serve to kill the animals therein.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

A rodent-exterminating torpedo comprising a wrapper having an explosivecompound arranged thereon and within its opposite ends, said wrapperwith its compound being rolled to form spiral convolutions, the oppositefree ends of the Wrapper projecting outwardly from the torpedo, a fuseextending centrally and part way into one end of the torpedo, anddetachable bands arranged between said free extended ends and ends ofthe torpedo to retain the compound within the wrapper, and one of saidbands also servin@ to hold the fuse within the torpedo.

n testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
